Active record WHERE clause not working?

well, trat's weird...

I'm having the same code like:

Code:

function get_page($url = 'home'){
    $this->db->where('url', $url);
    $q = $this->db->get('content');
    //$q = $this->db->query('SELECT * FROM content WHERE url = ?', $url);
    if($q->num_rows() == 1) return $q->row(); else return FALSE;
        
}

    function getpage(){
        $this->output->enable_profiler(TRUE);
        $this->get_page('http://www.example.com');
    }

and on the profiler I get:

DATABASE: citest QUERIES: 1
0.0003
SELECT * FROM (`content`) WHERE `url` = 'http://www.example.com'

It seems to be all right...
